A witness who saw her boyfriend being stabbed by a deranged man testified she was terrified when he turned and began coming at her with the bloody knife.“He reminded me of the movie ‘Jaws’ when the shark gets blood,” testified Tosha Ramos who saw suspect Hoyt Mitchell Hobbs stab her boyfriend, Brian Dedmon, several times with a knife. “He had a blank, creepy face.”Dedmon, 24, suffered stab wounds to his chest, hand, back and stomach but survived. Hobbs, 57, who lived at the same residence as Dedmon, Ramos and Ramos’ father, remains held under bond charged with attempted murder and aggravated assault.Ramos testified Hobbs had been acting strange all week and had closed himself inside his room without coming out for days.
